Description

Technical Field

[0001] This utility model relates to the field of continuous roll bag production technology, specifically a heat sealing device for continuous roll bag production. Background Technology

[0002] Roll bags are packaging containers made of plastic film, offering moisture-proof, waterproof, dustproof, and shockproof properties. They are widely used in the food, supermarket, and e-commerce logistics industries. Their price is influenced by factors such as materials, size, thickness, and printing, resulting in a diverse range of products on the market. Environmental protection, safety, and storage conditions must be considered during use to ensure product quality and safety.

[0003] In the processing of roll bags, heat sealing is a crucial step, as it determines the strength and sealing of the bag opening.

[0004] In traditional processes, heat sealing and punching are two separate steps that need to be performed separately. This increases the number of steps and changeover time in the production process. Because heat sealing and punching need to be performed separately, the number of times the equipment is used increases accordingly, leading to faster equipment wear and higher maintenance costs. Furthermore, punching after heat sealing is difficult to guarantee in terms of accuracy and position because the heat-sealed material has already solidified, which can affect the sealing performance of the roll bags. Therefore, a heat sealing device for the production of roll bags is proposed to solve the above problems. Utility Model Content

The perforating plate 393 is located below the heat-sealing plate 392. A feeding roller 18 and a support roller 19 are fixedly connected to one side of the mounting plate 1, and a winding roller 191 for winding the continuous roll bag is provided at the bottom of the connecting plate 11.

[0026] As a preferred technical solution in this embodiment: In actual use, the operator can pull the raw material of the continuous roll bag that needs to be heat-sealed from the feeding roller 18, place it between the heat-sealing seat 391 and the support platform 171, and pass it around the support roller 19 so that its other end is connected to the winding roller 191. Then, the operator can control the winding roller 191 to rotate, thereby achieving the effect of winding the raw material of the continuous roll bag. At the same time, the operator can control the transmission motor 21 to drive the transmission shaft 22 to rotate. During the rotation of the transmission shaft 22, the transmission cam 23 can be driven to rotate. During the rotation of the transmission cam 23, the linkage component 3 can be driven to drive the heat-sealing seat 391 to move back and forth. When the heat-sealing seat 391 moves towards the support platform 171, it can drive the heat-sealing plate 392 to achieve the effect of adhering to the raw material of the continuous roll bag, thereby achieving the heat-sealing of the continuous roll bag. At the same time, the perforated plate 393 located at the bottom of the heat-sealing plate 392 can achieve the effect of perforating the continuous roll, thereby effectively improving its working efficiency.

[0027] The technical effects of the above solution are as follows: by setting a heat-sealing seat 391 and setting a heat-sealing plate 392 and a perforating plate 393 on the heat-sealing seat 391, it can effectively achieve the effect of heat-sealing and perforating the raw material of the roll bag during use; it effectively achieves the effect of completing two processes at the same time, which can increase the processing efficiency on the one hand and reduce the processing cost on the other hand.

[0028] Example 2:

[0029] Please see Figure 1-5 To achieve continuous heat sealing and perforation of the roll bag, the linkage component 3 in this embodiment includes a linkage platform 31. A connecting rod 32 is fixedly connected to the linkage platform 31. The bottom of the connecting rod 32 is rotatably connected to the support plate 12, and the top of the connecting rod 32 penetrates the top plate 13 and is fixedly connected to a return spring 33. A return spring 33 is provided on the return spring 33 for resetting. A linkage column 34 is provided at the bottom of the linkage platform 31, and the linkage column 34 is at the same horizontal height as the transmission cam 23. A connecting arm 36 is rotatably connected to one end of the linkage platform 31, and the other end of the connecting arm 36 is rotatably connected to the fixed platform 16. A transmission arm 37 is rotatably connected to the other end of the linkage platform 31, and a transmission platform 38 is rotatably connected to the other end of the transmission arm 37. Two transmission columns 39 are fixedly connected to the transmission platform 38, and the two transmission columns 39 are slidably connected to the mounting plate 1. The other ends of both transmission columns 39 are fixedly connected to the heat sealing seat 391.

[0030] As a preferred technical solution in this embodiment: In actual use, when the operator controls the transmission motor 21 to drive the transmission cam 23 to rotate, the protruding part of the transmission cam 23 contacts the linkage column 34 and causes the linkage column 34 to move. During the displacement of the linkage column 34, the linkage table 31 can be driven to rotate. During the rotation of the linkage table 31, the angle between it and the transmission arm 37 will increase, so that the other end of the transmission arm 37 can drive the transmission table 38 to move. When the transmission table 38 moves, it can drive the transmission column 39 so that the heat sealing seat 391 can achieve the effect of heat sealing and perforation of the continuous roll bag material. At the same time, when the linkage table 31 rotates, it can rotate the return spring 33 to store energy. When the protruding part of the transmission cam 23 disengages from the linkage column 34, the connecting rod 32 will be reset under the action of the return spring 33, thereby controlling the linkage table 31 to drive the transmission arm 37 and the transmission table 38 to reset. During the continuous rotation of the transmission cam 23, the heat sealing seat 391 can achieve the effect of continuous heat sealing and perforation of the continuous roll bag material.

[0031] The technical effects brought about by the above embodiments are as follows: by setting up the linkage table 31 and the transmission arm 37, it can achieve a good transmission effect on the heat sealing seat 391 under the action of the transmission cam 23; by setting up the return spring 33, it can effectively control the heat sealing seat 391 to achieve the effect of moving back and forth under the cooperation of the transmission cam 23, thereby effectively performing continuous heat sealing and punching of the raw material of the roll bag.

[0032] The working principle of the above embodiments is as follows:

[0033] 1. In actual use, the operator can pull the raw material of the continuous roll bag that needs to be heat-sealed from the feeding roller 18, place it between the heat-sealing seat 391 and the support platform 171, and pass it around the support roller 19 so that its other end is connected to the winding roller 191. Then, the operator can control the winding roller 191 to rotate, thereby achieving the effect of winding the raw material of the continuous roll bag. At the same time, the operator can control the transmission motor 21 to drive the transmission shaft 22 to rotate. During the rotation of the transmission shaft 22, it can drive the transmission cam 23 to rotate. During the rotation of the transmission cam 23, it can drive the linkage component 3 to drive the heat-sealing seat 391 to move back and forth. When the heat-sealing seat 391 moves towards the support platform 171, it can drive the heat-sealing plate 392 to achieve the effect of adhering to the raw material of the continuous roll bag, thereby achieving the heat-sealing of the continuous roll bag. At the same time, the perforated plate 393 located at the bottom of the heat-sealing plate 392 can achieve the effect of perforating the continuous roll, thereby effectively improving its working efficiency.

[0034] II. In actual use, when the operator controls the transmission motor 21 to drive the transmission cam 23 to rotate, the protruding part of the transmission cam 23 contacts the linkage column 34, causing the linkage column 34 to move. During the displacement of the linkage column 34, the linkage table 31 can be driven to rotate. During the rotation of the linkage table 31, the angle between it and the transmission arm 37 will increase, so that the other end of the transmission arm 37 can drive the transmission table 38 to move. When the transmission table 38 moves, it can drive the transmission column 39, so that the heat sealing seat 391 can achieve the effect of heat sealing and perforation of the continuous roll bag material. At the same time, when the linkage table 31 rotates, it can rotate the return spring 33 to store energy. When the protruding part of the transmission cam 23 disengages from the linkage column 34, the connecting rod 32 will be reset under the action of the return spring 33, thereby controlling the linkage table 31 to drive the transmission arm 37 and the transmission table 38 to reset. During the continuous rotation of the transmission cam 23, the heat sealing seat 391 can achieve the effect of continuous heat sealing and perforation of the continuous roll bag material.
